My Office Hours between 10 A.M to 5 P.M .I am managing 16 client PCs which is remotely placed. I want to know the network status of every client PCs.I need an automatic trigger mail ,when the network connection is lost in any one of the Client PCs during office hours.I am a self study learner.I don't have an idea to develop the shell script.So Please give me a shell script. Please help me out of this problem.
mail id : upload.XXX@example.com.
Why use a mail? Why not ping them from your machine?
Because Alert Mail concept is useful to monitor the network connections when the network connection is lost and I have to take necessary steps to solve this issue.Already I had developed a shell Script a for network monitoring about the current network status.But I want the Network status through one mail when the network connection is lost.
mail eg:
If the 10th client PC Network Connection is lost,then I want to get a mail like as,
Please check the network connection of this 10th client PC.
Help me out - how do you plan to deliver that mail once the connection is lost?
Actually the plan is ,I want to ping 16 IP address and get the status through mail once when the connection is lost.I have mentioned the 16 IP addresses as follows,
10.66.1.133
10.66.6.133
10.66.7.133
10.66.0.133
10.66.1.5
10.66.2.133
10.66.4.133
10.66.3.133
10.66.5.133
10.66.2.5
10.66.3.5
10.66.7.5
10.66.0.5
10.66.6.5
10.66.4.5
10.66.5.5
I had developed a Network Monitoring script which is useful to monitoring the network and display the current network status of up and down.But I want to know the Network status through mail once when the connection is lost in any one of the 16 client PCs during office hours( 10.00 A.M to 5.00 P.M).My developed script is as follows, Can u develop the below script for Network monitoring through mail concept.I need a mail alert when the network connection is lost.Please help me out.

Replace the second while loop with e.g.
mail -s "IPs down" upload.XXX@example.com < $DownlistFilePath
to receive a mail with all down IPs.
First of all thanks to rudic for putting great effort to develop a script,
I think you are a genious
But I want to ping ip continuously from 10.00 A.M to 5.00 P.M, ( time specifications is important or else shell script continuously checking ip address to get a automatic triggering mail when network connection is lost)
When I am executing a shell script , I want to ping IP address morning 10.00 A.M to 5.00 P.M continuously,I want to get a mail once when the network connection is lost( for 16 IP address).( checking process continuously)
when I am executing a shell script ,I don't want to get the output from a terminal.But I just want to get a mail once when network connection is lost.This checking process is between 10 A.M to 5.00 P.M (continuous process)
sample example code for One IP Address :
if ping $ip > /dev/null
then
echo " " > /dev/null
else
echo " $branchcode-$branchname-$ip is down " >> mailcontent
mail -s " IPs down " upload.XXX@example.com < mailcontent
fi
Use cron to run that script every n minutes from 10:00h till 17:00h. If you replace the second while loop with a mail command there won't be any terminal output (which cron would send per mail anyhow, so you could skip mailing in your script...)
Can u please replace the mail concept in while loop and please mention the cron entries in crontab.
I don't know How can I replace the mail concept in while loop and cron entries in crontab too.Please modify the shell script for mail concept in while loop and please mention the cron entries in crontab for 10.00 A.M to 5.00 P.M.Please give me a complete shell script for mail concept and cron entries too.
Actually I want to ping continuously and then I want to get a mail when the connection is lost.If Network cuts down in any 16 ip that time only I want to get a one mail ip is down.
Well, try this (untested!):
#!/bin/bash
UplistFilePath="/root/Uplist.txt"
DownlistFilePath="/root/Downlist.txt"
rm -rf $UplistFilePath
rm -rf $DownlistFilePath
while IFS="\t" read $ip $branchname $branchcode
do ping -c 1 -W 1 $ip > /dev/null && { RES=up; FN=$UplistFilePath; } || { RES=down; FN=$DownlistFilePath; }
printf "%s %s of IPaddress %s is %s.", $branchcode, $branchname, $ip, $RES > "$FN"
done < IPfile.txt
[ -s "$DownlistFilePath" ] && cat "$DownlistFilePath"
use a crontab entry like
MAILTO=upload.XXX@example.com
*/5 10-17 * * 1-5 yourpath/yourscript
Your crontab may need a different syntax, though. And, all of this is not tested, so please read man pages and try to eradicate errors yourself...
